Rare borings infest brachiopod shells in Pleistocene fore-reef deposits of Jamaica (86 shells 35 valves) and Barbados (53 shells 49 valves). Only one example of the sponge domicile Entobia isp. was found, infesting Tichosina sp. cf. T. bartletti (Dall) from Jamaica. Predatory drillholes, Oichnus ispp., were more common. One Terebratulina sp. cf. T. palmeri Cooper from Barbados was perforated by Oichnus paraboloides Bromley; two further Terebratulina and one Argyrotheca sp. ct. A. barrettiana (Davidson), all from Jamaica, were bored by Oichnus simplex Bromley. This is a similar order of magnitude of predatory boreholes as most post-Paleozoic brachiopod faunas reported in the literature. This is the first record of O. simplex from the Manchioneal Formation of Jamaica and the first record of O. paraboloides from Barbados.
